| contents | The Pierre Auger Observatory has recently undergone a major upgrade, called AugerPrime, tailored to answer the current most pressing questions in the ultra-high-energy cosmic ray (UHECR) detection. The AugerPrime upgrade consists of the addition, on top of each station, of a scintillator detector, to separate the muonic and electromagnetic component of the shower for better primary identification, and of a radio detector to measure the emission of air showers in 30-80 MHz range. An additional small diameter photomultiplier is installed in each station to increase the dynamic range for signal detection. New electronic modules, installed on all stations, provide a sufficient number of channels for the readout of the additional detectors, as well as faster sampling, increased dynamic range and processing capability. In this contribution we summarize the performance of the new electronic modules with respect to the requirements, describe the verification procedure and give the results in the laboratory tests compared to the performance in the field. |
